Resolutions array is the safest option. You can also manipulate through
minResolution/maxResolution or minScale/maxScale. (Which in the end
populate a resolutions array).
Just a quick request for further clarification though. I understand
that maxExtent should not be set in an event. I was mostly just
trying to do some debugging to figure out what was going on as the
extents were being changed, so that I could prove to myself that the
extent was being accepted as maxRestrictedExtent (and eventually I
threw maxExtent in there through desperation). I plan on setting
whatever needs to be set in an onClick function for the button the
user clicks on accepting a particular area of the map.
But setting maxRestrictedExtent definitely works for panning, and
doesn't help with restricting outward zooming. Do you feel that
adding a resolutions array would be my only other option?
